Communications Processor Applications
Use the SEL-2600 RTD Module in combination with the SEL-2030 Commu-
nications Processor to enhance many protection and monitoring applications. The
SEL-2030 monitors temperature data from the SEL-2600, performs threshold com-
parisons, and sends control commands to a protective relay.
The applications shown in Figure 2, Figure 3, and Figure 4 on page 7 repre-
sent a few of the possible configurations using the SEL-2600 and the SEL-2030.
Contact SEL for help in applying these products in other configurations.
Program the SEL-2030 to perform four automated steps:
Step 1. Receive temperature data from the SEL-2600.
Step 2. Store the temperature data in memory.
Step 3. Perform temperature threshold comparisons.
Step 4. Issue control commands to a protective relay based on the
temperature comparisons.
The next few pages describe how to configure the SEL-2030 to perform the
four automated steps shown above. It is assumed that the SEL-2600 is connected to
Serial Port 4 of the SEL-2030. Refer to the SEL-2030 Communications Processor
Reference Manual and the SEL-2030 Communications Processor User’s Guide for
further information on programming concepts.
Receive Temperature Data
Connect the SEL-2600 to the SEL-2030 using an SEL-2800 Fiber-Optic
Transceiver and fiber-optic cable C801FD. Set the port settings of the SEL-2030
as shown.
